SYSTEM AND METHOD FOR EXAMINATION OF DYNAMIC BULGING THROUGH ANALYZING LEVEL FREQUENCY OF BREAK SURFACE

摘要

PURPOSE: A system is provided to take an actions while working by previously predicting the dynamic bulging having a bad effect on the work through the analysis of a break surface level and tracing the cause to occur the instability of the break surface. CONSTITUTION: A method for the examination of dynamic bulging comprises the steps of: measuring the level of the change in a break surface and analyzing the frequency of the change in a continuous molder; outputting the movement distance of the dynamic bulging by multiplying a period obtained from the analyzed frequency with the molding speed of the continuous molder; and outputting a position where the dynamic bulging occurs by comparing the movement distance of dynamic bulging with the distance between rolls in a specific segment of the continuous molder.
